EYEGLASS MOUN'IING.

3, 1911. a Serial No. 346,885.

Be it known thatI, Lno F. bany, in the countyof Albany and State of New York, have invented certain new and useful Improvements in Eyeglass-Mountings; and I to be a full, clear, and exact description of the same, referencebeing had to the accompanying drawings. formin 'a part of the specification, and to the re erence-numerals marked thereon.

My present invention relates to improvements in eyeglasses and ithas for its object to provide guard attaching portions havin pliable loops'or bends therein so formedand arranged .relatively' to the parts of the mounting as to afford a considerable range of adjustment for the guards in a direction forwardly vand rearwardly of the plane of nose guard in this instance belng seflfo'r ward. vFig. 2 is a View similar to Fig. 1 showm'g the nose guard offset toward the rear, and Fig. 3 represents a central horraontal section through'the attaching por-;

tions showing the relative arrangement of the bridge end and the adjustable loop or bend of one of theguards.

Similarreference numerals in the several figures indicate similar parts.

The present invention, provides an improved manner of mounting thc'nose guards adapted to be adjusted or set by the optician so as to properly fit each individual ose, and when so adjusted'thcy retain their relative adjustments, and in the present in- An'r, of Al- I do hereby declare the following.

as well as to permit adjustment of'the (guards to provide for different a,

clip; thence turns'forwardly or "tion transverse of the stance it consists in"providingthe nose or. bend arranged in plane, and having I lens or mounting at a point substantially in the plane of the rear surface of the lens, or

substantially so, and extending forwardly therefrom and thence inwardly and finally rearwardly to form the loop, and the rearformed opening toward the rear and lying practically forward 'of'the rear surface'of the lens.

My invention in the present-instance is shown applied to eyeglasses of the rimless type, and the bridge and guards are'attached to, the lenses by means of a'ttaching devices similar to those shown in my prior Patent in' these respects. 7

The bridge '1 in the present instance is of the vertically opening type having its end extending downwardly and thence extendingoutwardlyjbeyond the inner edge of the lens to form an attaching arm 2, a clip 3 being fitted over the lens edge and liaving'a g wardly-extending arm carrying the nose the adjustable loop thus -No. 691,345, although of course it will be understood thatthe invention is not limited strap at arranged to cooperate withfthe atftaching arm of the bridgeto hold; itin cooperative relation with the lens; and secured between the latter and the attaching arm of the bridge, is'the attaching arm 5 of" the "nose guard. This guard arm in the present instance extends to the inner in adire'cplane 'of the lenses, extending to a point at or in front of the forward surface of the lens when the guard edge of the occupies an intermediate or forward adj-ustr ment, the arm thence turning inwardly and finally extending rearwardly to form the horizontal adjustable bend 6,'and the rearwardly-extending arm 7 of the bend thus formed isprovided with a suitable nose guard. The nose guard may be attached to the supporting arm either as a separate part, or it may be formed integrally there.- with. as may be desired, the latter means of transversely 0 attachment being employed in the present instance, and the particular form of guard shown embodying the downwardly-extending nose-bearing portion 8 having its upper end attached to the guard supporting arm 7, and having a rearwardly offset pad 9, but it will be understood of course that the inventionis not limited in this respect, as guards of various forms may be used.

In fitting eyeglassesto noses of different shapes, it is usually necessary for-the optician to adjust the guards in a direction forwardly or rearwardly of the plane of the lenses to insure the positioning of the lenses at the proper distance in front of the wearers eyes, as well as to adjust the guards inwardly or outwardly to enable them to obtain a firm hold on noses of different widths, or to allow for variations in pupilary distances. A relative forward or rearward adjustment of the guards is obtained according to the present invention, by bending the loop in the guard supporting arm at different points, this operation being conveniently accomplished by means of the ordinary opticianspliers, it being obvious that by vary ing the location of this bend in the loop of the guard su porting arm in a direction I f the plane of the lenses, a corresponding adjustment of greater degree is given the nose guard, the full and dotted lines in Fig. 3 indicating the relative positions of the bend in the nose guards when the latter are in the forward and rear positions. These bends of the guard supporting arm are preferably open loops having their attached ends fixed to the lens or mounting at a point in, or in proximity to the'plane of the rear surface of the lens so as to enable an extreme rearward adjustment of the guard, one methodof attaching theparts to accomplish this result beingshown in the present embodiment, and the attaching portionof the bridge is so arranged as to clear the guard supporting arm in order to enable ample adjustment of the loop or bend thereof, the bridge shown in the present'embodiment having its ends a leading downwardly to a point between the inner and outer arms of the loop, and as the latter are arranged between the inner edges of the lenses and arevin substantially the plane of the lenses, these parts do not protrude unduly beyond the forward and rear lens surfaces, so that the mounting is compact and presents a neat appearance,

, andwhen' the guards have been properly adjustedby the Optician, they will retain 3 their adjustments to insure a perfect fit on the wearers nose. In the particular form of lens attaching device shown, the close proximity of the fixed armof the adjustable I loop may serve to hold the clip firmly in c0- operative relation with the lens.

I claim as my invention:

1. In eyeglasses, the combination with the lenses,and a bridge spring-connecting them, of nose guards having attaching arms com posed of pliable material bent to form horizontal loops opening toward the rear of the mounting, each loop being adapted to be bent at different points to adjust the guard forward or rearward and having one arm proceeding from the mounting at a point in rear of the forward surface of the lenses to extend freely through the plane of the latter, and carrying the nose guard on its free end.

2.111 eyeglasses, the combination with the lenses, and a suitable bridge connecting them, of nose guards and attaching arms for the guards composed of pliable material each having a horizontal adjustable loop formed therein arranged between the proximate edges of the lenses, and opening toward the rear of the mounting, one end of the loop being fixed to the mounting at a point at or in rear of the rear planeof the lens, the free end of the loop carrying the nose guard.

3. In eyeglasses, the combination with a lens, and a bridge having its end extending downwardly; thence outwardly to the lens, of a nose guard having an attaching portion composed of pliable material and provided with a horizontal loop arranged substantially in the plane of the lens, the arms of the loop being arranged on opposite sides of the vertical line of the downwardly-em tending portionof the bridge. one-arm being fixed. to the mounting and the other arm carrying the nose guard.

4 In eyeglasses, the combination with a lens, of a bridge having an attaching portion extendingoutwardlybeyond the inner edge of the lens, a nose guard having an attaching portion overlapping the rear surface of the lens between the latter and the attaching portion of the bridge, and pro vided with a horizontal loop opposite to the inner edge of the lens and openingtoward tion with the lens and the free end of the loop being connected to said guard attaching portion, and the other end of the loop carrying the nose guard, and means forsecuring the bridge and guard attaching portions to the lens.

5. In eyeglasses, the combination with a lens, and a clip having a lens-edge bearing portion, a strap at one sideand an attaching lugat the other side overlapping the lens, of abridge having an attaching portion fitting beneath said strap and overlapping the lens edge opposite to the attaching lug of the clip, and a nose guard having an attaching portion fitting beneath the said strap betweentheattaching portion of the bridge and the lens and provided with a horizontal loop, a portion of the latter cooperating With the clip to hold it in cooperative relation with the lens and the free and of the loop carrying the nose I guard, and means for securing said clip and the bridge and guard attaching portlons to the lens.

6. In eyeglasses, the combination with a lens, of a nose guard having an outwardly extending. attaching portion secured to the rear face of the lens and a horizontal loop opening toward the rear of the mounting 10 and a bridge having an attaching portion secured over the attachingv portion of the guard.
